Christian Schwarz 5c2356988e page_service: add benchmark for batching (#9820) ...

This PR adds two benchmark to demonstrate the effect of server-side
getpage request batching added in
https://github.com/neondatabase/neon/pull/9321.

For the CPU usage, I found the the `prometheus` crate's built-in CPU
usage accounts the seconds at integer granularity. That's not enough you
reduce the target benchmark runtime for local iteration. So, add a new
`libmetrics` metric and report that.

The benchmarks are disabled because [on our benchmark nodes, timer
resolution isn't high
enough](https://neondb.slack.com/archives/C059ZC138NR/p1732264223207449).
They work (no statement about quality) on my bare-metal devbox.

They will be refined and enabled once we find a fix. Candidates at time
of writing are:
- https://github.com/neondatabase/neon/pull/9822
- https://github.com/neondatabase/neon/pull/9851
